Understanding What Lies Beneath
Most homeowners only see the visible layer of their roof – the shingles or tiles. However, beneath that outer layer is a complex system of components that keep your home dry and structurally sound. At LS Roofing Henley-on-Thames, we have inspected and repaired countless roofs in Henley-on-Thames, Oxfordshire, and we know that what lies beneath is just as important as what you see on top.
The Roof Deck: The Foundation of Your Roof
The roof deck is the structural base that supports the entire roofing system. If this deck has been exposed to moisture for too long, it may become soft, warped, or rotted. A compromised roof deck can lead to sagging, leaks, and costly structural repairs.
Underlayment: The Unsung Hero
Between the deck and the outer layer lies the underlayment – usually felt or a synthetic material. Its job is to create a secondary water barrier. Over time, underlayment can deteriorate, leaving your roof vulnerable to wind-driven rain and moisture ingress.
Flashing and Valleys: Key Leak Points
Flashing protects joints, chimneys, vents, and valleys from water intrusion. When flashing corrodes or pulls away, leaks often follow. Many homeowners are unaware of hidden flashing issues until water stains appear on ceilings.
Insulation and Ventilation: Protecting Your Home’s Efficiency
Proper ventilation and insulation beneath the roof help regulate temperature, prevent condensation, and reduce the risk of mould. Poor airflow can cause premature shingle failure and raise energy bills.
Hidden Pests and Damage
An old roof may also be harbouring pests such as insects, birds, or rodents that can damage insulation and wiring. Regular inspections can uncover these problems before they become a major issue.
Conclusion
Your roof is more than just the outer layer of shingles – it is a multi-layered system designed to protect your entire home. For homeowners in Henley-on-Thames, Oxfordshire, LS Roofing Henley-on-Thames provides expert inspections to reveal what’s really happening beneath the surface. Whether it’s worn underlayment, damaged decking, or corroded flashing, addressing these issues early can save you from expensive repairs later.
